2009 WRX Coilover Install
by Subachad on May.06, 2010, under Installs, Suspension
Pretty much any car designed for the masses is going to be somewhat neutral in many aspects. Suspension is a great example of this as the average person doesn’t want a firm ride or the worry of breaking the front bumper cover off when getting just a little to snug to a curb. Automotive enthusiasts however, are a slightly different breed. We notice that split second gab between turning the wheel and the car following along. We are ok with a little more noise, we want the car to be firm and responsive.
Springs vs Coilovers – The debate will continue. Personally I say springs. You can get a nice firm responsive whip without being overly jaring. Coilovers really limit the amount of suspension travel you have. For example, you might need to jack up your car 4 inches before the tire leaves the ground. With coilovers, it’s only going to be about an inch. The nice thing about coilovers such as installed here, are the advantages of setting ride height, spring rate and shock firmness.
This install is about coilovers. The install is pretty much the same as a regular spring install with a few key differences.
Epic Springs and a Downpipe Install on a 2009 WRX Hatch
by Subachad on Apr.19, 2010, under Engine, Installs, Suspension
Another spring install on a WRX along with a Downpipe install. This time its a 2009 Impreza WRX Hatchback. Not only do these Epic Lowering Springs give the car a much nicer stance, it’s also a great suspension modification to improve the handling of the WRX without sacrificing ride quality.

WRX Half Shaft March 2009
by Subachad on Dec.18, 2009, under Automotive
Installs, like a lot of things in life; the only thing certain is uncertainty. In fact, planning on something going wrong or something holding you up is how I go into pretty much any install. Sometimes it’s something minor… other times… well, this was not one of those other times.
This is the first of a couple installs that night so I pretty much just dug right in. Half shaft installs on an Impreza are pretty straight forward.
1. Loosen large nut holding the half shaft to the knuckle. This can be done with a 32mm socket, long breaker bar. You will need to uh… put your back into it as they say, this will be tight.
2. Lift corner you are working on.
3. Remove wheel.
4. Disconnect Sway Bar.
5. Remove the bolt that holds in the ball joint or the nut holding the ball joint to the control arm. I usually remove both and let the car choose which is separated.
6. Unbolt the tie rod.
7. With a large hammer, beat the control arm near the ball joint. The vibrations will help separate the ball joint from the control arm.
8. Once separated you should have enough movement to pull the knuckle out of the way. This maintains your alignment as well since you are not unbolting the strut.
9. The inside where it goes to the transmission will either pop out or have a pin which you will need a punch to tap out.
Pretty much as easily as you read this, is how the install went. Once the shaft was pulled, we compared it to the replacement… to find the wrong part DOH!
Impreza RSLRA Gets A New Race Friendly Core Support
by Subachad on Sep.19, 2009, under Installs
What is a race friendly core support anyway? Well, I’m not really sure. What I do know is if you want to run a V Mount intercooler and radiator setup then you are going to need some room. The stock bumper beam, upper core support, and lower brace just don’t allow the freedom one needs to run enough radiator or intercooler. As for the bumper, well it was only attached by the sides so we decided to make some more room, make it stronger, and add lightness.
This project actually started a few nights ago. We laid out some general plans based on what it was we were trying to achieve. Intercooler and radiator fitment allow for easy to service and maximum cooling. We also didn’t want to lose any chassis rigidity. When considering chassis mods take into account the actual forces being applied otherwise you might be adding strength and weight with no real benefit. Despite my wifes beliefs about my memory abilities, I was able to reach in and pull some helpful ques from my past.
Corolla lovers, the RWD type from the 80′s, not the newer corollas of today, are big on hanging on to that front bumper or even replacing it with something better to aid in chassis strength. Perhaps it’s an attempt to bring out the inner Takumi or delivery driver, but I just don’t think anyone would have one of these tossable cars and not drive it. They know about chassis torsional flex and do a lot to avoid it. That’s a lot of words to say, we need to keep the strength in the lower bar. To improve on it even more, I pulled a que from Lou, former host of Muscle Car. Well he too was a stickler for chassis rigidity which resulted in chassis tricks for all sorts of unibody and frame based cars. He would basically trim out enough of a factoy connection and place strong tubing or box in key flex areas. I also thought back to a Trucks episode where they shortened a frame and rather than cut it straight, they cut down then over then down again to maximize te welding area. Whoever said you can’t learn something by watching tv?
2005 Aveo Suspension and Handling Observations
by Subachad on Sep.14, 2009, under Automotive
No one is going to mistake the Aveo for a Race car. Race cars are fast and very responsive. This article is about making the Aveo more responsive while keeping cash in my pocket.
First off, a personal definition of responsive. To me a car needs to feel responsive in a few areas. Throttle response, braking, and handling. This article will focus mostly on the handling aspect. Keep in mind this is an Aveo, so keeping the budget to a minimum while not harming fuel economy will limit some of the results, but can also make for more interesting reading into the world of Aveo tuning.
The most basic approach to improving a cars handling is lowering springs and large wheels with low profile tires. That’s “out of budget” for this project, Not only that, but there are so many other aspects involved in a cars ability to handle well. For example chassis rigidity and flex. Follow along for the other tricks to making a car handle without breaking any banks.
Lowering Springs: Lowering the center of gravity is a great way to reduce body roll and keep the car on track. This is by far the most popular method and looks good too. The key is to match the lowering springs with a good set of struts to avoid a bouncy ride. Springs run about $200. I decided to go with H&R as they were the only springs available at the time for the Aveo. Eibachs are now available, they don’t lower it as much, but I suspect the ride quality is better.
